ABSTRACT
reservoir
gridblock-size outcrop (10 X 100 m) of
fluvio-deltaic sandstones to evaluate the importance of internal heterogeneity for a
hypothetical waterflood displacement process. Using a dataset based on probe permeameter
measurements taken from two vertical transects representing "wells" (5 cm
sampling) and one "core" sample (exhaustive 2-mm-spaced sampling), we evaluate
the permeability variability at different lengthscales, the correlation characteristics
(structure of the variogram function), and importance of volume and data support. We then
relate these statistical measures to the sedimentology.
